Cafe Rosa on Steam
store.steampowered.com
Cafe Rosa is a cafe management simulator. Serve food to unique customers and earn coins. Manage your own cafe by upgrading the facilities and changing the interior. Dive into the world of cafe ownership and watch your business flourish!

This is one seems very simple both in terms of graphics (IMO not very important for tycoon/economic strategy type games) and even gameplay. But I decided to include this to support indie developers.
